为探讨壮秧营养剂对软盘旱育秧和苗床旱育秧的壮秧效果及机理 ,以水稻品种中 - 1 0 0 ,湘早籼 2 8号和中优早 81为供试材料 ,比较研究了 4种壮秧营养剂对水稻软盘旱育和苗床旱育秧苗的生理影响 .结果表明 :壮秧营养剂 T1 ,T2 和 T4对苗床旱育秧苗的根数和茎基宽比对照显著提高 ;壮秧营养剂 T1 ,T2 和 T3对软盘旱育秧苗的生理影响主要表现为根干重、根系α-萘胺氧化力、根系总吸收表面积和活跃表面积、叶片含氮量及叶绿素含量提高的幅度较大 ,T1 和 T2 所表现出的效应差异不大 ,而 T3表现出较大的优势 .生产上应用时 ,早稻软盘旱育秧壮秧营养剂每盘的施用量以 8～ 1 2 g（434孔型 ,直径 2 .2 cm）...

kinds of rice seedling nutrient agents were used to compare their physiological effects on early rice seedling under the culture condition of dry nursery or carrier plate. The results are as follows: Most measuring value are higher than that of control, such as dry matter weight of root and plant, number of white root, width of stem, α naphthaleneamine oxidation ability, root total absorbing surface area, root active absorbing surface area, contents of leaf chlorophyll, proline, N, P and K . Growing seedlings treated with the rice seedling nut...
